Cha Gio (Vietnamese Spring/Egg Rolls)

For about two dozen egg rolls, you'll need:

1 lb ground pork
1/2 to 1 lb shrimp, minced or ground in a food processor
1 package spring roll or rice paper wrappers
1 small section bean thread vermicelli. They're sold individually or in packages, but the packages will tie a small bundle together. You just need one.
1 cup dried mushrooms, soaked and sliced, or 1 cup Tree/Wood Ear Fungus/Mushroom, soaked
1 large onion, minced or grated
1 or 2 carrots, peeled and grated
1 egg, beaten
1 tsp salt, adjust to taste
1 tsp sugar, adjust to taste
1 tsp black pepper, adjust to taste
2 tsp nuoc mam (Vietnamese fish sauce), adjust to taste

Optional: Ground turkey or chicken may be substituted for the pork. Add shredded cabbage if you'd like more vegetables. Add minced crab to make it even more flavorful. Vegetarians may substitute the meats with fresh tofu, just make sure to drain the excess water.
